The COVID-19 pandemic presents monumental challenges. A newly emerged virus to which the world’s population has no immunity, coupled with the fast movement of individuals across the globe, has set the stage for an outbreak of proportions not seen within the last century.

For infection with this virus to happen, it must come into contact with the eyes, nose, or mouth. This happens when droplets produced by an infected particular person (by way of speaking, coughing or sneezing), land on the face of another person. These infectious droplets can journey as much as 6 ft, which is the reason to promote social distancing. Touching a surface that is contaminated with infectious droplets and then touching one’s own eyes, nose or mouth, is another way for infection to occur. Therefore, the important thing to avoiding infection is to have these areas of the face covered.

In hospitals, face masks and goggles are typically used to stop exposure to infectious droplets. Nevertheless, face masks shortages are occurring because of interruptions within the provide chain, which is deeply rooted in China and disrupted by the pandemic. Some health care workers have been pressured to resort to scarves and bandannas in a final-ditch try and protect themselves while providing care. Even when plentiful, face masks are not with out problems. As soon as they change into wet from the humidity in exhaled air, they lose effectiveness. In addition, some people touch their face more typically to adjust the masks, which will increase the risk of an infection if the arms are contaminated.

Fabric masks, though better than nothing, have been shown to be less protective than medical-grade face masks.

We believe that face shields provide a better solution. There are many types, however all use clear plastic materials attached to a headpiece to cover the eyes, nostril and mouth, thereby stopping infectious droplets from contacting these areas the place the virus can enter the body. They cover more of the face than masks and prevent the wearer from touching their face. Importantly, face shields are durable, can be cleaned after use, reused repeatedly, and for many people are more comfortable than face masks. Because these shields are reusable and are diversified across the supply chains of a number of industries, the present supply is less limited than for face masks. They’ll even be made at home with objects from office provide and craft stores.

Every health care worker wants a face shield for protection at work. While face masks are nonetheless needed in some situations, implementation of face shields will tremendously reduce the need for face masks and prolong the limited national provide of masks. Engineers have produced designs for face shields which can be within the public domain, and fabrication at scale is relatively simple. To make sure that every health care worker has a face shield, production will need to ramp up to meet the demand by way of current producers and recruitment of additional factories. Because the design is easy, large fast production wouldn’t be difficult.

As soon as the health care workpower is provided, distribution to the public ought to begin, with a goal to provide a face shield to each person within the country. It needs to be worn anytime an individual leaves their home, while in any public place, and even at work. Although shelter-at-house approaches are wanted to “bend the curve” of this pandemic, the ensuing societal disruption limits the time that political leaders are prepared to maintain such measures. As soon as every individual is shielded, however, reducing restrictions on movement would carry less risk. Universal shielding may reduce reliance on social distancing since infectious droplets cannot reach the face of prone individuals. Handwashing, nevertheless, would remain essential to keep people from infecting themselves with virus found on the hands after touching contaminated surfaces.
